PRODUCT DESCRIPTION
Concrete elements reinforced with light steel mesh framed expanded polystyrene(EPS) panel
Light duty steel mesh framed expanded polystyrene panel is made of polystyrene foam plastic plate, and both sides are coverd high tensile steel wire mesh panel. The steel wire mesh is diagonally inserted accross polystyrene plate with galvanized steel wire, 3D EPS panel is connected by spot welding. Our products are followed our National Standard JGJ / T 269-2012.
Light duty steel mesh framed expanded polystyrene panel is applied to design and construction of which load-bearing wall component and floor board members for seismic fortification intensity of 8 degrees or less, building of 10m or less, floor number of 3 floors or less.
The 3D paltes are used flame retardant molded ploystyrene foam(EPS) board.The main performance index should be conformed to the rule of below sheet.
